Title: Fire boat 39
Post by: Garabaldy on September 09, 2008, 11:02:14 pm
Ok i started working on this tonight.  I have decided to do a proper build blog because all you guys can give me your input and keep me right!  This is my 2nd build and first scratch build.  Im looking forward to the planking.  I have a pile of 1.5mm x 5mm obechi planks, possibly i would have been better using 10mm wide planks but its too late now......

heres some info on the build;

The boat is 1016mm x 210mm wide.  Twin props, i intend to use 2 MFA torpedo 850s turning 3 blade brass props.  I will be using an action mixer too.  Of course because its a fireboat, there will be working fire monitors and lights to match.  Im still unddecided whether to use ply or plasticard to construct the superstructure.  Im familiar with plasticard but i find it warps very easily.  Does anyone else find this?

Heres all ive done so far, its not much but its a start!   Il start cutting wood tomorrow night.

Gary

I use plastic card a lot and don't have problems with warping. You do have to use the appropriate thickness, and brace if necessary.

hi there Gary

It is looking good   O0   an old saying my friend 'Cross that bridge when we get to it' - regarding building the superstructure.   Get the hull right first and then you will find building the superstructure and what materials to use will naturally fall into place.

With regard to the planking material; I notice you have opted for 5mm wide - in actual fact this may be a bonus to you; meaning - you will have a slightly stronger hull, due to the fact that you have a greater gluing area on the edges.

Remember Gary to purchase for yourself a boat-load of plastic clamps - springy clamps or the curler clips the aluminium ones.  The reason for this, is, if you clamp them over the planks to keep them level between the frames.

2nd last thing, is more of a tip/suggestion - you may already have done this - it is difficult to tell on the photograph you have shown - go over your drawn pencil line with a black or blue biro - you will find this does not sink into the plywood so quickly and then fade away; leaving you to struggle to find out where the line is.

Is there any chance of you putting a pic of the Plan on the Forum here; so we can have a look at it?  KEEP THE GOOD WORK UP  O0 :)

Blluebird, thanks for reminding me about the clamps.  Thats one thing i dont have!  As funds are low at the moment im trying to be as resourcfull as possible so would this sort of thing be ok for clamps - http://www.istockphoto.com/file_thumbview_approve/1878182/2/istockphoto_1878182_stationary_clips.jpg providing they have a big enough 'bite'?  Im relieved to hear that about the planks width, they are tiny!

I shall get a picture of the plan up tonight, after i cut out my frames of course! O0

P.S. i know the picture is terrible and doesn't really show anything other than a sheet of plywood!  Sorry.

Gary,

Do you have a 'Pound Shop' near? They usually have plastic clamps for sale at £1 for several. Much better, and probably cheaper than the ones you showed, although the larger of these could be used - the spring ones not the paper clips.

unfortunatly i live in a pretty remote place and only get to go to the big city once a month or so but my work has thousnds of those clips i showed ::)

Although after hearing a pound shop has that sort of stuff i will deffinatly be taking a look the next time im there.

Thanks,

Gary

hi there Gary

I am attaching 2 pics - the top one shows the variety of clips that I have - I have collected these over a period of time - from the Pound shops, paper shops, you name it...even from the hairdressers and, if you look on the far right- top row you will see the granny clips some of the hairdressers use - ....

the other pic - pin vice drill - you may have one of these already, but, if not - they are only 2-3 quid on ebay - with a selection of very small drills they are extremely useful.   The idea is, pre-drill the planks with the tiny small drill before you push the pin through - it prevents the plank from splitting when you are planking.

hope this helps.

Ive been thinking long and hard about this build again.  I know at this stage when im cutting out the frames it would be easier to drill the necessary holes for the propellor shafts in the frames but because im having a little difficulty figuring out where they will be im wondering if in this case it would be easier to "cross the bridge" when the time comes around?  Anyway i havent got as far as cutting the wood yet anyway, only marked most of it out as the pictures will show.  Also i have a picture of the plan.  If anyone would like to see the full size picture of the plan as its far clearer than the resized one pm me.

I have marked out the areas in the frames to be removed which you can see in the pictures, I have left a frame thickness of 15mm all the way round and left it slightly thicker at the bottomo f the frame where the keel joins to the frame.  I am yet to go over this with pen as bluebird suggested earlier because  im watching instinct which is an amazing movie.  I still need to mark out the notches in the frame for the keel joint too but this can wait.  Oh and the keel thickness is 20mm.

now its beer time ;D

Thanks,

Gary

Hi there Gary

Right, to plot the position of propeller shafts on your frames – it is quite easy to do.  :D But, bloody difficult to explain  ;D  so….we shall take it in easy steps.

Stage 1 – we need to put your main plan on a table; then you need a good steel ruler, plastic ruler, nice sharp pencil and a pair of drawing compass’ (you know the ones – they are used for drawing circles with.)    So, the first thing we do is on the view of the side of the model; we will locate the propeller shafts and we draw a centre line through the very centre of the propeller shaft on the side view plan.   This centre line goes well inside your hull.    In other words, on your particular hull, the centre line should pass Frame I; when you have drawn that centre line in; we need to draw in the frame positions at right-angles to your keel.   These are drawn in as dotted lines in my scribble to help you.    These must be at right-angles to your keel.

Stage 2 - move over to the drawing which shows the frames, the ones you have traced off to produce the ribs.   On this drawing you will see the position of the propeller shaft which has already been marked with a cross and a dotted circle to represent the propeller (on the plan).   

You will see the distance between the centre of the cross and the centre of your frames – it is called the prop shaft centre line.   This centre line runs parallel to your keel, at a set distance and in fact it never varies (on this particular model).  So, now you have 2 dimensions – these 2 dimensions are equal on both sides of the frame, port and starboard.   Now you have 2 plotting points from which to work, one from our side view plan and one from our frame plan.

Take your first frame, where the prop shaft begins to enter the hull; this looks as though it is frame K on your model.  Take a dimension from the bottom of your keel to where K dissects the centre line of the prop shaft – on your side view model – with a pair of compasses.   You move over to where you have drawn rib K on your plywood, on the centre line of Rib K you mark this height – from the keel up over.   This marks the position of the height of where the prop shaft enters the hull – now what we need to plot is the distance from the centre line of the frame to your centre line of your prop shaft.  This dimension comes from your frame plan which is marked with the cross.   Mark this position on Rib K on the plywood.

Move on then to the next rib and do exactly the same on Rib J, same procedure mark your height from the keel and also mark your distance.   This produces what is called a ‘plot’ of where your propeller shaft will pass through your frames and this in turn will give you an indication of where to drill holes through your frames for the position of your prop shafts.

I hope you can understand my above description.    I am attaching a couple of scribbles – hey I hope you can understand them.    If not give a yell and will have another go at an explanation for ya.   Neee worries.

Aye

Thanks bluebird that all makes perfect sense.

How did you determine that the shaft goes through frame I?  Im not disputing this, just interested in how to work this out for myself in the future.

Also what is your take on the size of hole to drill in the frames for the shaft?  Is it wise to make the hole slightly larger than it needs to be as an allowance when installing the shaft?   

Thanks,

Gary
Title: Re: Fire boat 39
Post by: John W E on September 11, 2008, 02:31:32 pm
Gary hi there

to answer your question about the prop shaft length and how did I determine that it should come through Frame I, to be honest, I had to do some guesstomation work  O0  looking at your photograph and knowing that the model is 40'' long - I had to determine, the rough position where you would like to put the motors - it looks as though you may place them at the back of the midship section - roughly about 14-18 inches from the stern.   Therefore I picked a 12'' standard prop shaft to work with (for length) and based the calculations around that length of prop shaft.   

To answer your second question, normally I will cut or drill the holes for the prop shaft through the frames about 6-10 mm larger than the diameter of the prop tube.  This, as you say, allows for mis-alignment during building and soforth and also allows you to relign, with packing, the tubes.  When you are happy with them, I normally epoxy the prop tubes in place.

However, I only fit the tubes after I have planked and fibre glassed all of the hull. 

I know some people fit the tubes first - which I have done in the past and then plank - but, I found it very awkward to sand and fibre glass around the tubes without damaging them.

Title: Re: Fire boat 39
Post by: Garabaldy on September 11, 2008, 11:49:39 pm
Perfect, again O0

Plotted the points out.  It would appear the point where the shaft exits the hull is also where the frame meets the hull meaning when i cut the hole in the frame (its frame k by the way) it be nearer a notch than a hull.  I assume it will be easier to create this hull once the hull has been built and im installing the shafts.  The one thing which concerns me is when i am doing this i will probably strike the brass pins when drilling and make a real dogs dinner.  Will i be safe enough to just not use brass pins in the area to avoid this?

Thanks,

Gary
Title: Re: Fire boat 39
Post by: John W E on September 12, 2008, 10:58:09 am
Gary good morning there

when you refer to the hole for the prop shaft in K frame, is it very close to where the planking is going to be?

if it is, what I normally do in this case, rather than pin with brass pins in this area of the frame; as you suggest, just glue and clamp the planks there.

What you could do, is, instead of drilling say a 10mm hole in the frame K; drill a 6mm hole and use that hole as a pilot hole to open up when you are ready to put the prop shafts in.

Last but not least, forgot to mention - another great clamp source - clothes pegs - the springed ones plastic and wooden - but remember to put a bit of cellotape over the jaws of the wooden pegs to stop the glue from sticking to the peg.

Hello,

Ive been hard at work!  Ive got all my frames keel etc cut out now as you can see from the pictures.

When i traced the keel i just used the side elevation on the plan and traced right up to deck level which i though was the most sensible thing to do.  Now when i dry fit all my frames to the keel it would appear the frames at the stern are too high.  (the same problem at the front woops sorry i  mean bow!)   You can see in the picture i have drawn on a couple of lines roughly where deck level should be?  Or have i done somthing wrong when i traced out the keel shape?  I also included a picture showing the frame nearest the stern against the line drawing to show its been copied exactly as per the drawing.

Other than that though, everythings going good (i think!)

Post by: Garabaldy on September 16, 2008, 08:21:45 am
I have been thinking about this again on the way to work,

Is it possible i have drawn the slots on the keel facing the wrong way?  All the frames nearest the bow i projected the line on the drawing on to the keel then proceeded to draw the slot "towards" the bow"  On the frames nearest the stern i did the same but drew the slots "towards" the stern.  If i did this the other way around and drew the frames nearest the stern towards the hull and vice versa this would been the 2 frames at the stern would be  "further down the hill" on the keel there for would sit lower and the same would be at the bow.  Im not sure if this is true as the hill isn't very steep at the stern and the frame would have to move quite far before i would see much height change.   :-\

Oh well, back to drinking coffee and pretending to work :angel:
Title: Re: Fire boat 39
Post by: dougal99 on September 16, 2008, 01:12:18 pm
A good start would be to check the height of the drawn frames with the height of the deck at each frame position on the side elevation on the plan. I have found that there are sometimes inaccuracies even on plans bought from plans libraries. At least you haven't started gluing yet.

Post by: John W E on September 17, 2008, 10:33:12 am
Hi there Gary

I think by your posting on another topic - that you may have sorted your problem out with regard to the height of the frames - so let's do a checklist  O0

you have cut all the notches in your frames to take the deck edge stringer - the stringer which runs around the top of your frames; level with your deck

you have secured all your frames to a building board; and they are all in the correct position

you hare fared all the frames in with a sanding block, meaning you have checked that no frames are higher or lower than the next one to it; and that they all run in line smoothly - so when you put a piece of planking strip over any frame, it sits on the edge squarely & that you are happy

You have added strips either side of the keel? between the frames, so that your first plank lies on it and gives more support........

all singing and dancing

happy building there mate

Post by: Garabaldy on September 17, 2008, 01:22:00 pm
after alot of head scratching and measuring i came to the conclusion the lines for the 2 rear frames were slightly too high, this combined with some other minor inaccuracies added up to about 8mm - so i chopped it off the top of the frame.  Sorted!

Notches cut, 1 question though, the string should be flush with the edge of the frame so that we can plank over it?

Im not sure qhat you mean about adding the strips either side of the keel, what should these strips be made from?

securing and fairing will be finished off tonight ;D
Title: Re: Fire boat 39
Post by: John W E on September 17, 2008, 01:28:44 pm
Gary hi there

Your stringers should be flush, to enable you to plank over them; yes

The strips I referred to, which go either side of the keel - well, I normally make them from 1/4 square Obechi.   If you have a look on the Whaleback build thread; where I am actually fitting stringers onto the hull, you will see a photograph where I have added these pieces between the frames, either side of the keel.

I will do a scribble if you want one  O0   got a new printer/scanner so I need to go to HongKong and back to let me post the scribble to ya.

ok the hulls planked.  Ive not made as good a job of it as i hoped i which is why i havent posted any pictures yet.  I just need to do alot of sanding and it should be ok.  I l post some pictures tonight.

My motors arrived today.  You may have seen elsewhere on the forum i opted for brushless.  I  got 2 tornado c3530 thumper 340watt 1100kv which will hopefully give me some flexibility with batteries etc....  I ordered 2 35amp sea king speed controllers from himodel too which should arrive over the next few days.  Im just looking wondering how to mount the motors now.  Is anyone aware of any problems using brass or any other metal to mount brushless motors?
Title: Re: Fire boat 39

some pictures of progress.   hopefully get a coat of resin on tomorrow

i have also included a photo of the motor.  1 problem i can see is the small circlip on the shaft which means a larger clearance hole is needed on the motor mount.

You know what - I have had a good look at your hull and planking and for a person who has never planked a hull before - you have made a dam good job of it - SO NEVER PUT YOURSELF DOWN - ask your mam when you were born, before you walked did you complete the London Marathon ....

update:

Got everything running.  Fitted water intakes/outlets.  I know the water scoop isnt scale but i have hidden it as best i can just between the rudder and prop.  I tested it out before i put the silicone tubing on and a got a spout of water a good few inches high!  The brushless motors run sweet.  The speed controllers are a bit funny with this "double click" action to reverse them but apart from that they are good.  They are musical too haha!  By that i mean they sing when the motor is running, its quite bizzare and sounds very futuristic.  The bath test went well though.  I was only running one motor but even with that on 3/4 throttle half the bath water ended up on the floor!  Very powerfull!  I think im going to add a 2nd 12v battery nearer the stern to increase running times + i need the ballast.  the next size down from 7amp should do it i think.  heres the pics

ive been quite busy.  Ive smoothed the hull out and now its nearly ready to recieve paint.  I bought a load of y shaped tee pieces and some super flexible pvc tubing for the monitors.  Water pump installed and it works well.  I built a board which i have mounted the actuating servos for the microswitchs to switch the pumps and lights.  Decks are currently being cut and glued.   I have decided to make access hatches large and beyond the superstructures so im working out how to seal them.  I think i read somewhere else on the forum that you can fit in the shelf around the hatch for the removable deck section to sit on then run a thin  bead of silicone glue round it and wrap the removable deck in cling film then fit it.  Leave to dry.  Then the theory is the silicone wont stick to the cling film and there should be a pretty perfect silicon seal left?  Does this work?  If it does it seems ideal and simple.

Pictures soon.

quick update - sorry no pictures....

She had her maiden voyage on sunday.  WOW the whole boat lifts right out of the water at full throttle.  Really impressive!  Ive managed to squeeze loads of functions, lights, water canons, i can aim 1 of the fire monitors via the transmitter too, tank steering.  She handles really well in the watter.  Extremely agile.  Took on quite alot of water though as i dont have the hatches properly sealed.  Well ive just about finished doing that now though.  Hopefully get to the loch again this weekend and il try and get some pictures this time.

Looking good Garabaldy  :-))

What plans are you using? Looks like a plan I've seen in 'Model Boats' many years ago...
Just a word of caution about the water piping, try slipping a "doubler" piece of silicon tubing over the ends to
 prevent any pipes coming adrift under pressure.

 Will you be cooling the motors (motor mounts)?

cheers martin.

Its the fireboat 39 plans the link is http://www.myhobbystore.com/2066/Colyer-Fireboat-39-MM1373.html

The motor  mounts are made from wood so im a little deep to try and cool them now.  The motors don't even get warm when running though.  On the maiden voyage she was going flat out most of the time and even the speed controllers were still cold - it was a very cold scottish winter afternoon though!

I think im just going to put small tie wraps on the pipes to stop them coming off.  Ive been looking around for a cheap quick connect to break the pipe to remove the wheel house but all i can find are really expensive ones.

That is a great job with the Fire boat you put together there. If you have any picture of her in the water love to see her doing her thing, also maybe you can puit her on U-tube and we can see the fireboat in acton on video moving around when she is ready. But really Great JOb   Garabaldy :-))

Heres a little bit of progress.  I still have more detailing to do but im getting there.  Even though i have concentrated my efforts on my other build lately. 

heres the pics.  My old boy was in control when the photos were being taken so there isnt actually a photo of her going flat out.  You can tell by the wake he only had one motor running too as he didnt realise it was "tank steering" bless! 

During this sail i actually managed to do a bit of damage.  The loch is super shallow and the boat hit the bottom a few times.  I've cracked off one of the plastic bushes on the port shaft and both rudder shafts have been bent backwards.  Nothing too serious though.

Yeah thats on loch of skene again.  It was boxing day - bitter cold!  Its a cracking loch to sail on just gotta watch out for the shallow bits which seem to be around the entrance of the boat house.  Yeah the fire monitors work really well, i get a squirt of about 4 or 5 metres i think.  I would have a picture of them working but i forgot the connecting hose on this sail :D

Hi Gary

Did you ever finish your fireboat.
